Scalable Electronic Health Record Management System Using a Dual-Channel Blockchain Hyperledger Fabric

Abstract

Communication and information technologies have accelerated the implementation of electronic medical records, but at the same time, have put patient privacy, information security and health data at risk. An alternative to address the problem of security and privacy of medical data is the use of blockchain. Scalability has become one of the biggest challenges facing the development of blockchain-based electronic health records (EHRs). The purpose of this article is to implement and test a scalable blockchain-based EHR management system. For this reason, we present a scalable blockchain-based EHR management architecture. In this paper, we propose an EHR management model based on entities and user roles, adapt, and then implement with Hyperledger Fabric in a two-channel configuration. We develop a prototype in Fabric using a one-and two-channel configuration. We then designed and conducted an experiment to verify the performance of the proposed scheme in terms of scalability improvement. This scalable blockchain-based EHR management solution, such as the Hyperledger Fabric platform, offers a viable alternative to address scalability issues, as well as to protect patient's privacy and the security of their medical data.

Development of the automated decision-making system synthesis method in the management of information security channels

“…However, possible options for predicting information leakage channels and eliminating such channels are not explored. The work [18] proposed the implementation and testing of a scalable EHR management system based on blockchain. The disadvantage of this work is the two-channel transmission of decision-making system for managing information security channels, which takes into account uncertainty in determining information leakage channels and allows to ensure the required level of security.…”

Blockchain and Healthcare: A Critical Analysis of Progress and Challenges in the Last Five Years

“…Dual-channel blockchain architecture based on Hyperledger Fabric is suggested for electronic health record (EHR) administration to scale up medical data management while guaranteeing effectiveness and security [87]. Access control and privacy are elevated even higher in blockchain-based systems with biometric authentication [87]. These security measures are essential for maintaining the accuracy and privacy of medical data across the whole blockchain-based healthcare ecosystem.…”
